8 Days After Adding Instant Shudder Fixx to My Transmission #productreviews #j2review

8 days have passed since adding Instant Shudder Fixx to the transmission (6R80) in my 2015 Lincoln Navigator and so far, so good. I still intend on draining the old fluid which has 110,000 miles on it, changing the filter and putting LubeGard with Instand Shudder Fixx in with new fluid to see how far it takes me.

I had the same problem. It got bad enough that I started driving my hooptee. I was about to by a transmission, but saw your video and tried the Lube Guard. Its been about a year now and the shudder is still in the wind! Great product and thank you for putting me on that trail……

My 2015 Lincoln Navigator started the shudder at 100k miles. I changed the fluid and filter...shudder went away instantly. Now with 132k miles, it still does not shudder. I didn't use any additive. Thanks for the great videos!

4.7L of Mercon V, new filter, 1 tube of Lubegard, 45, 000KM, 8 months, snow storms, 4wd for hours upon hours, hauling trailers etc etc and not so much as a quiver out of my 4R75E in my old 2004 New Style F150 with a 5.4L. Truck now has well over 250, 000KM on it and all original and it runs and shifts like it did out of the showroom. I cannot remember EVER as a Professional Licensed Technician where I've ever endorsed "Witch Doctor In A Bottle" but let me tell ya this stuff works like a champ when added to a new filter and fluid change (NOT A FLUSH)!

Amsoil signature series atf works well. Add seafoam before you drain, should clean everything

I used this on my old jeep 246k miles 120k on the new transmission. And it's working really well for me. It used to shift slow and now she's like a rocket ship lol. But tbh it really works .

Hi, Is it ok to add it without changing the oil & filter?

[Therealestrunnerluda]

How was your shudder. How bad was it. Mine was random only happen twice really bad like I'm riding on really bumpy rumble strips on both sides. It was so bad I had to stop I checked my wheels and nothing weird and then I smelled burning transmission fluid. Just wondering if this was the same type of thing going on with you. 2014 1500 LT Z71.

I added it to my 2014 Silverado that had just had a fluid and filter change when the shudder started. It has NOT helped mine at all....

My rx300 is giving me this malarchy rn

[blumie]

The only oil I'd be sticking in a zf6 or 6r80 is zf lifeguard 6 or equivalent anything else will definitely destroy your trans

[danielbrowniel]

I just bought some, still have NO IDEA how to add it to my 2012 Camry SE 4 banger, I'll drill a damn hole if I have to, jk jk

[jonnyhitch]
